Wooden corner member

ABSTRACT

A wooden corner member includes a first segment and a second segment. Each of the first and second segments includes a first wood piece and a second wood piece. The first and second wood pieces are stacked on and bonded to each other. The first wood pieces of the first and second segments are bonded to each other along a first bonding line. The second wood pieces of the first and second segments are bonded to each other along a second bonding line. The first and second bonding lines are staggered from each other.

CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority from Chinese utility model patent application no. 202020162793.8, filed on Feb. 11, 2020.

FIELD

The disclosure relates to a stair handrail, more particularly to a wooden corner member for a stair handrail.

BACKGROUND

A large section of the trunk or a main branch of a tree can be cut and sculpted into various articles based on the design, but is relatively expensive. In order to save on manufacturing cost, as shown in FIG. 1, a conventional wooden corner member 9 for serving as a corner portion of a wooden handrail (not shown) may include two wood segments 91 each of which is made by bonding a plurality of small wood pieces 911. The wood segments 91 may be fastened to each other using fasteners 92 so as to prevent the wood segments 91 from moving relative to each other along a bonding line (X).

However, a stress concentration at the bonding line (X) may cause breaking or damaging of the conventional wooden corner member 9 after being used for a period of time. In addition, a stress concentration at the place where the fasteners 92 are mounted may also cause the braking or damaging of the conventional wooden corner member 9.

SUMMARY

Therefore, an object of the disclosure is to provide a wooden corner member for a stair handrail, which has good durability, and which may be made in a relatively low-cost way.

According to the disclosure, a wooden corner member for a stair handrail includes a first segment and a second segment. Each of the first and second segments includes a first wood piece and a second wood piece. The first and second wood pieces are stacked on and bonded to each other. The first wood pieces of the first and second segments are bonded to each other along a first bonding line. The second wood pieces of the first and second segments are bonded to each other along a second bonding line. The first and second bonding lines are staggered from each other.

Because, in the wooden corner member of the present disclosure, each of the first and second segments is made by bonding the first and second wood pieces, the wooden corner member may be made in a relatively low-cost way. In addition, the first and second bonding lines are staggered from each other to permit stress in the wooden corner member to be dispersed, and thus, the wooden corner member may have good durability in comparison with the conventional wooden corner member.

DETAILED DESCRIPTION

Before the disclosure is described in greater detail, it should be noted that where considered appropriate, reference numerals have been repeated among the figures to indicate corresponding or analogous elements, which may optionally have similar characteristics.

To aid in describing the disclosure, directional terms may be used in the specification and claims to describe portions of the present disclosure (e.g., front, rear, left, right, top, bottom, etc.). These directional definitions are intended to merely assist in describing and claiming the disclosure and are not intended to limit the disclosure in any way.

Referring to FIGS. 2 and 3, a wooden corner member 1 according to a first embodiment of the disclosure may be provided for a stair handrail and is shown to include a first segment 11 and a second segment 11′. Each of the first and second segments 11, 11′ includes a first wood piece 111 and a second wood piece 112 which are bonded to and stacked on each other.

The first segment 11 extends mainly in a longitudinal direction (X), and the second segment 11′ extends mainly in a transverse direction (Y) relative to the longitudinal direction (X).

The first and second wood pieces 111, 112 in each of the first and second segments 11, 11′ are stacked on each other in a stacking direction (Z) transverse to both the longitudinal and transverse directions (X, Y). In an embodiment shown in FIGS. 2 and 3, the stacking direction (Z) is an upright direction, and the second wood piece 112 is stacked under the first wood piece 111.

The first wood pieces 111 of the first and second segments 11, 11′ are bonded to each other along a first bonding line (L1). The second wood pieces 112 of the first and second segments 11, 11′ are bonded to each other along a second bonding line (L2). The first and second bonding lines (L1, L2) are staggered from each other. In other words, projections of the first and second bonding lines (L1, L2) in the stacking direction (Z) are staggered from each other.

It should be noted that although each of the first and second segments 11, 11′ includes two wood pieces 111, 112 in this embodiment, in other embodiment, each of the first and second segments 11, 11′ may include three or more wood pieces as long as the numbers of the wood pieces respectively in the first and second segments 11, 11′ are the same.

In addition, each of the first and second boding lines (L1, L2) is a straight line. In other embodiment, each of the first and second boding lines (L1, L2) may be, but not limited to, a curved line or a saw-toothed line.

In this case, each of the first and second segments 11, 11′ of the wooden corner member 1 may be made in a relatively low-cost way by bonding the first and second wood pieces 111, 112 together. The first and second bonding lines (L1, L2) are staggered from each other to permit stress in the wooden corner member 1 to be dispersed, and thus, the wooden corner member 1 may have good durability. Moreover, because the first and second bonding lines (L1, L2) are staggered from each other, the first and second segments 11, 11′ are less likely to move relative to each other. As such, it is unnecessary to fasten the first and second segments 11, 11′ using the fasteners as in the prior art, and the first and second segments 11, 11′ may be bonded to each other using an adhesive.

FIGS. 4 and 5 illustrate a wooden corner member 1 according to a second embodiment of the disclosure. The second embodiment is similar to the first embodiment except that in the second embodiment, each of the first and second segments 11, 11′ further includes a third wood piece 113. The first, second, third wood pieces 111, 112, 113 are stacked on and bonded to each other in the stacking direction (Z). The second wood piece 112 is stacked between the first and third wood pieces 111, 113. The third wood pieces 113 of the first and second segments 11, 11′ are bonded to each other along a third bonding line (L3). The projections of the second and third bonding lines (L2, L3) in the stacking direction (Z) are staggered from each other, while the projections of the first and third bonding lines (L1, L3) in the stacking direction (Z) are arranged to overlap with each other.

After bonding the first and second segments 11, 11′ together to obtain the wooden corner member 1, the wooden corner member 1 may be further processed along the contour shown by the imaginary line in FIG. 4 to obtain a more aesthetic product 2 shown in FIG. 6.

In sum, because each of the first and second segments 11, 11′ in the wooden corner member 1 is made by bonding the first, second, and third wood pieces 111, 112, 113, the wooden corner member 1 may be made in a relatively low-cost way. In addition, the first and second bonding lines (L1, L2) and/or the second and third bonding lines (L2, L3) are staggered from each other to permit stress in the wooden corner member 1 to be dispersed, and thus, the wooden corner member 1 may have good durability in comparison with the conventional wooden corner member.
